Kench's Devour is toxic for allied players

This is not the 1st time it happened to me where I was matched with toxic Tahm Kench. The game, which is ranked game, was not going well and he used Devour on me and probably on allies after which he threw me/allies into the enemies.

Its nice in normal games between friends but when we play competetive game and things are not going well this get worst and helps enemies win the game

Ever since this champ came out i knew this was going to happen - an ability that can be used on allies for negative purpose. Something about Kench's Devourer should be done otherwise people would still continue to use Devourer for negative purpose

For instance I should be able to have much greater control when Ally Kench use Devourer on me. Like lets say I can exit Devour after 0.5 seconds in my desired direction where he wont be able to do it for 2 seconds

here's the problem

After 1 second, Devour can be recast into Regurgitate Regurgitate while Tahm Kench's belly is full. Allied champions can exit at will AFTER THE SAME DELAY.
